Originally there were supposed to be 151 jail calls released on Monday, but Zimmerman's defense attorney Mark O'Mara objected to the release of 145 calls that he says have nothing to do with Zimmerman's next bond hearing.

He wrote on a blog, "The majority of the phone calls are personal and irrelevant to the charges against Mr. Zimmerman." He also wrote, "The public release of these phone calls could jeopardize the privacy of friends and family of Mr. Zimmerman who are unrelated to the case."

O'Mara did not object to the release of the six calls.

Zimmerman is charged with second-degree murder. He is pleading not guilty, claiming self-defense.
